An AC power supply with frequency 10 Hz is connected to a resistor (with resistance R), a capacitor (with capacitance C) and an inductor (with inductance L). If the power supply's frequency is increased to 30 Hz, how does the capacitive reactance (Xc) change? a) Xe increases by a factor of 9. b) Xc increases by a factor of 3. c) There is no change in Xc- d) Xc decreases by a factor of 3.
